Prevention and Treatment Methods for Tuberculosis in Farmed Nutria
Tuberculosis (Tubercu[.sis) is a chronic infectious disease shared by livestock, poultry, fur-bearing animals and humans, occurring as endemic outbreaks. Tuberculosis is characterized by the formation of caseated and calcified tuberculous nodules in the internal organs. (Pathogen) The pathogen of tuberculosis

Prevention and Treatment of Rabies in Nutria Breeding
1) Prodromal stage. During this period, affected nutrias are briefly depressed and move slowly; the symptoms at this stage are not easy to notice. 2) Excitation stage. Affected nutrias show excitement and aggressive behavior, lunging at people and other animals, biting, clawing, and tearing everything they encounter. Affected nutrias can injure their own tongue, teeth, and gums and can break their lower teeth. Affected nutrias refuse food, do not drink water, and often swallow various objects placed in the cage. The violent stage recurs repeatedly; during episodes the affected nutrias groan, salivate excessively, and have diarrhea. 3) Paralysis stage. During this stage the paralysis process intensifies, manifesting as swaying of the hindquarters and paralysis of the hind limbs. Body temperature drops. Sick nutrias cannot rise, lie down unconsciously, and die in spasms and convulsions. (2) Necropsy: the gastrointestinal mucosa is congested or hemorrhagic; the liver is dark red and flaccid; the spleen is slightly enlarged, and there are also cases in which it is 2-3 times larger than normal. Anemia is found in the kidneys, and the boundary between the cortical layer and the medullary layer disappears. In some cases there is pulmonary hemorrhage. In the brain, congestion appears due to blood vessels being highly filled and dilated with blood. The fluid in the ventricles increases, and pinpoint hemorrhages are often found in the brain tissue. 4) Prevention. The measure for preventing rabies on nutria farms is to resolutely prevent outside dogs from entering the nutria breeding area; keepers must also be vaccinated against rabies. If rabies-infected nutrias are found on the farm, a blockade must be resolutely implemented, and the epidemic situation must be reported promptly to the higher competent department. Resolutely prevent sick nutrias on the farm from escaping off the farm; confirmed rabies-infected nutrias or carcasses of nutrias that died of the disease must all be burned or deeply buried; individuals that have not developed the disease must be examined one by one so that sick nutrias are detected in time. Healthy nutrias must all be injected with rabies hyperimmune serum, and 7-10 days later injected with rabies vaccine. Counting from the last case that died of rabies, the blockade is lifted after 2 months.

How to prevent and treat mastitis in nutria breeding
[Causes of mastitis in nutria]Mastitis is mostly caused by infection of the mammary tissue, such as traumatic infection from bites to the udder by the young, or the mother nutria having an abundant milk supply, causing the udder to become engorged, while the young have weak suckling ability or die, leading to long-term accumulation of milk and causing mastitis

How to prevent diseases in nutria farming
For infectious diseases of nutria, in addition to specific prevention, epidemic prevention and quarantine systems should be strictly observed, and the veterinary hygiene order of the farm and the feed mixing room should be maintained at all times. The specific measures are as follows: (1) Entry of outside personnel into the farm should be strictly controlled or prohibited; when necessary

How to Do a Good Job in Disease Resistance and Epidemic Prevention and Control in Nutria Farming
Measures to be taken when an epidemic occurs on a nutria farm Once an epidemic occurs on a nutria farm, the principle of "early, fast, strict, small" should be followed, and decisive measures should be taken to quickly stamp it out. (1) Confirm the diagnosis as soon as possible and report the epidemic When an infectious disease is suspected, immediately

Prevention and Treatment Methods for Iridoviral Fish Disease in Pufferfish
Iridoviral fish disease affects many fish during the high water temperature period in the farming of pufferfish juveniles and adults. Through observation of the iridovirus in diseased fish using Giemsa staining, iridoviral fish disease occurs concurrently with botulism and vibriosis, and is a viral disease caused by infection with bacterial and parasitic fish diseases.

A Detailed Guide to the Prevention and Treatment of Vibriosis in Farmed Pufferfish
[Symptoms of pufferfish vibriosis] The pathogen is Vibrio, with a growth temperature of 101Z-35C and an optimum temperature of around 25C; the growth salinity range is 0.5%-6%, and can even reach 7%, with an optimum salinity of around 1%; the growth pH range is 68, with an optimum of around 8. Diseased fish show gastrointestinal bleeding

Prevention and Control Methods and Key Technical Points for Fulminant Disease in Cultured Puffer Fish
[Symptoms of fulminant disease in puffer fish]The main symptoms of diseased puffer fish are congestion at the base of each fin and in the fin rays; in severe cases, the fin rays, upper and lower jaws, eyes, and the area from the base of the dorsal fin to the caudal fin all show severe congestion. Sometimes there is bleeding in the orbital cavity and exophthalmos (bulging eyes). In some cases the gills show varying degrees of decay with abundant mucus.

How to prevent and treat linear hepatic hemorrhage disease in farmed pufferfish
[Symptoms of linear hepatic hemorrhage disease in pufferfish] Sick pufferfish have a darkened body color, with the color from in front of the eyes to the snout noticeably paler; sometimes the body color of the pufferfish becomes pale while the area in front of the eyes becomes even paler and pallid. Sometimes the bases of the caudal fin, anal fin and dorsal fin are congested. When the abdomen of the fish is cut open, 1-2 obvious linear blood stasis marks can be seen on the liver, all extending upward from the left side of the abdomen to the right side. There is no food in the intestine, and the intestinal wall is sometimes slightly congested; sometimes severely affected fish show unusually frantic, random darting behavior, similar to the symptoms of white mouth disease in pufferfish. Linear hepatic hemorrhage disease in pufferfish has a high mortality rate, and there is currently no effective treatment method, so we adopt the policy of giving priority to prevention with treatment as a supplement. Regulate the water environment well, frequently siphon out waste, and frequently change the water, especially the bottom layer of water, which should be replaced regularly. When sick fish are found, remove and destroy them promptly. The following treatment measures were taken for the affected ponds and achieved certain results.

What are the prevention and treatment methods for gill rot disease in pufferfish?
[Symptoms of gill rot disease in pufferfish] Diseased pufferfish move sluggishly, have darkened body color, have difficulty breathing, swim slowly in the upper water layer or near the pond edge, and have reduced appetite. When the gill cover is opened, increased mucus on the gill filaments is visible to the naked eye; in severe cases, the tips are decayed and defective, and some gill filaments appear grayish-white, often
